Hi all, I'm using the Version 3.x is Esri's legacy JavaScript API, and based on this page https://support.esri.com/en/products/developers/web-apis/arcgis-api-for-javascript/3-37#deprecation/... it will became deprecated and discontinued after July 2022.

Will the version 3.xx still be working after "retired" date or I have to migrate it to version 4.xx to make it working ?

Hi @MuhammadAlza, that article is specific to the Web Optimizer, which will be retired in July 2022.

If you look at the Product Support page, you can see the lifecycle for each version of the ArcGIS API for JavaScript (both 3x and 4x): https://support.esri.com/en/Products/Developers/web-apis/arcgis-api-for-javascript/3-38#product-supp...

However, we do recommend migrating to 4x sooner rather than later, as the majority of the development work occurs there.
